Is chlorine dangerous at 0.5 ppm?
The permissible exposure limit of OSHA is 1 ppm.
What is the TLV for sulfur di oxide emission at work place?
2 ppm H.O.Rathour
How you convert ammonia liquid pounds to gas ppm?
You cant...Coz its not a ratio...You can find number of moles, weight, and etc but not ppm bcoz ppm is termed from composition
How to convert 10 ppm mole of H2O to ppm wt in natural gas?
10 ppm mole multiply by molecular weight of water then divided by sample density
What is the full form of ppm in gas?
Parts per million.
What is the maximum allowable limit of CO in the flu gas furnace?
400 ppm of air free

no

Is 36 ppm too high and is it dangerous?
It is impossible to tell you whether 36 ppm is dangerous if you do not tell us what substance it is you're concerned about.

Why is it dangerous to keep increasing the amount of CO2 in atmosphere?
We won't asphyxiate. But CO2 is a heat trapping gas, and it takes decades for the earth to adjust to any slight rise. Human activity has increased CO2 levels from 280 ppm prior to the industrial revolution to nearly 400 ppm today. We will pass 500 ppm before 2050, at the current rate. Many climate scientists believe 350 ppm may be the maximum sustainable level for CO2.
How much mercaptan is in natural gas?
1-3 ppm by volume
Is 228 ppm of natural gas unsafe?
(previous answer)"228 ppm of natural gas is not unsafe as long as there is no way for it to increase in concentration. 5000ppm in a confined space is considered explosive. Since 5000ppm is considered the lower explosive limit of natural gas, it is reasonable to assume that enough oxygen has been displaced to possibly cause asphyxiation."(improvement:)As a 33-year veteran HVAC contractor and Gas Fitter instructor, I believe that even 1 ppm of combustible gas is unsafe. The reason is that I have seen "safe" (low-level) gas leaks blossom to hazardous conditions within 1 hour. You cannot assume that 228 ppm of natural gas will remain at that level.Also, the lower explosive limit of natural gas is 4%, which converts to 40,000 ppm.
